PROBLEM TO BE SOLVED: To provide a method and apparatus for encoding and decoding a coding unit of a picture boundary.SOLUTION: A video decoding method comprises: a step 1710 of determining whether or not a first coding unit contains a region that deviates from a boundary of a current picture; a step 1720 of purging the data associated with a second coding unit that not deviates from the boundary of the current picture among at least one of the second coding unit generated by dividing the first coding unit based on a determination result; and a step 1730 of decoding the date associated with the second coding unit that does not deviate from the boundary of the current picture. 【課題】ピクチャ境界の符号化単位を復号化する方法及びその装置を提供する。【解決手段】映像復号化方法は、第１符号化単位が現在ピクチャの境界を外れた領域を含むか否かを判断する段階１７１０と、判断結果に基づいて、第１符号化単位を分割して生成された少なくとも１つの第２符号化単位のうち、現在ピクチャの境界を外れていない第２符号化単位に係わるデータをパージングする段階１７２０と、現在ピクチャの境界を外れていない第２符号化単位に係わるデータを復号化する段階１７３０と、を含む。【選択図】図１７
